Why are you adding in factors that he hasn't mentioned?

Because they are typical factors. Boats that sail close hauled also fall off
from time to time, especially when they are out for a daysail. Are you
suggesting that Ed was hard on the wind, eyes blazing as he went upwind as far
as possible?
Puh-lease.
Wally, you've been exposed as a simple and rather poor troll, trying to apply
exact math to someone casual comments about a daysail.
Shame on you. Launch your boat and you'll feel less bitter.
